It might be the fastest, most important water buoy ever invented. That would be the Emergency Integrated Lifesaving Lanyard or EMILY – a 25lb, 4ft-long, bright orange, red and yellow colored cylindrical buoy powered by a jet engine similar to a mini jet ski, and travels up to 22 MPH.

“EMILY is made of Kevlar and aircraft-grade composites and is virtually indestructible,” said inventor Tony Mulligan, CEO of Hydronalix, a maritime robotics company that developed EMILY along with the Office of Naval Research. “The devices can be thrown off a helicopter or bridge and then driven via remote control to whoever needs to be rescued.”
